Disabled terminators appear as distributed capacitance on the

bus. The IMP5111/ 5112 have been optimized to have only 3pF of

capacitance per output when in the disabled mode.

LINE

The IMP5111/ 5112, with their unique architecture, applies the

maximum amount of current regardless of line voltage until the

termination high threshold (2.85V) is reached.

The IMP5111/ 5112 are compatible with active negation drivers.

The devices will handle up to 60mA of sink current for drivers

which exceed the 2.85V output high level
